Create a cosmic horror-inspired, hyper-realistic image of a Mazinger entity with wings, set against the backdrop of a dark, gothic cityscape inspired by the 2019 anime 'Skyscraper 2 - Hero Dark City'. The entity should have Evangelion-style eyes and be composed of a manta ray made of pancakes. Incorporate elements of Slaanesh and The Thing, and ensure the image is highly detailed, with a focus on lifelike textures and atmospheric lighting. The image should be rendered in 4K/8K ultra HD, with a cinematic environment inspired by the works of Richard Mortensen and Wes Anderson.
